Title: Tyre pressure monitoring method providing different calibration data in different signal ranges
Inventor: MILLER THOMAS LEE
IPC: G01D3/024
Filed: 2006-10-23
Abstract: A tyre pressure monitoring system for a vehicle has a pressure sensor circuit (that includes an electronic control unit, a transmitter/receiver, and pressure sensor (94). A method of operating a tyre pressure monitoring system includes calibrating a tyre pressure sensor circuit in a first range and a second range and generating a first calibration data for the first range and second calibration data for the second range. The first calibration data and the second calibration data are stored in a memory of the tyre pressure sensing circuit. A data signal corresponding to the pressure is generated. The first or second calibration data is generated in response to the range of the data signal to form a selected calibration. The data signal is calibrated with the selected calibration to form a pressure indicative signal. The pressure indicative signal is transmitted to a receiver within the vehicle with a range status corresponding to the selected calibration. A pressure signal is formed in response to the pressure indicative signal and the range status and the tyre pressure monitoring system is operated with the pressure signal.

Title: Integrity checking method for a device in a computer network, which controls access to data; e.g. to prevent cheating in online game
Inventor: GRIMEN GISLE
IPC: G06F21/57
Filed: 2006-10-27
Abstract: A method and apparatus for transmitting data in systems such as computer networks, for example in client-server or peer-to-peer arrangements, is disclosed. Access to transmitted data received by a destination apparatus is limited by the provision of software code at the destination apparatus. The software code is arranged to produce a result which is a function of the state of the destination apparatus, and this result is used to access the data. For example, the result could be calculated using a checksum function. The software code may be either transmitted to the destination apparatus, for example along with the data it is used to access or from a separate server, or may be generated at the destination apparatus. The method and apparatus is particularly applicable in the field of on-line gaming, wherein the transmitted data is encrypted gaining data and the result of the software code provides the access key to the encrypted data. The invention can thus be used to prevent cheating.

Title: LED driver with current source
Inventor: STEELE COLIN
IPC: H05B44/00
Filed: 2006-12-21
Abstract: A driver apparatus is provided for controlling a light source array in a scanner. The apparatus has at least two light sources L1, L2, L3 used for illuminating a scan region on a target object, and light reflected from the target object is captured by a detector. The driver apparatus has a single integrated circuit IC comprising the processing means for processing image data received from the detector and the driver apparatus. A current source IS1 controls the flow of current through the light sources L1, L2, L3. In this way the LED switching circuitry S1, S2, S3 that controls an LED array is placed on the same integrated circuit (i.e. monolithic circuit) as the analogue processing circuitry that processes the image data, with the current source IS1 controlling the flow of current through the LEDs L1, L2, L3 in the LED array. The current source IS1 has the advantage of avoiding rapid changes or slope discontinuities in the current flowing through the LEDs L1, L2, L3, which would otherwise cause unwanted transient signals. A shunt path 50 comprising a switching device S4 may be provided in parallel with the LED array and switching array. The shunt path 50 has the advantage of enabling the switching sequence from one LED to another to be controlled such that a substantially constant current is drained from the supply (subject to any differences in the inherent current drawn by the Red, Green and Blue LEDs, respectively). The shunt path may have a second current source IS2.

Title: A handle assembly for a cleaning appliance
Inventor: WOOD RALPH MICHAEL
IPC: A47L9/32
Filed: 2007-08-09
Abstract: According to the invention there is provided a handle assembly 100 for a cleaning appliance such as a vacuum cleaner (10, fig 1). The handle assembly 100 comprises a slideably extendible wand 104 and a connecting portion 106. The connecting portion 106 further comprises a first locking arrangement 128 for releasably securing the handle assembly 100 to the main body of the cleaning appliance (10, fig 1), a second locking arrangement 126 for releasably locking the wand 104 in a pre-determined position with respect to the connecting portion 106 and an actuator 122. The actuator 122 is adapted and arranged to move the first and second locking arrangements 128, 126 between locked and unlocked positions, and the first locking arrangement 128 is also movable independently of the actuator 122. By providing such an arrangement, a single actuator 122 can be operated by a user to unlock both the first and second locking arrangements 128, 126 simultaneously. However, because the first locking arrangement 128 is independent of the actuator 122 it is possible to secure the handle assembly 100 to the main body 12 of the cleaning appliance 10 whilst keeping the wand 104 in a locked position. This is beneficial when the user wishes to return the cleaning appliance 10 to a floor cleaning mode without collapsing the wand 104.
